MOUNTING FOR SLIDING DOORS.

Specification of Letters Patent. I P t t J ly is, 191

Application filed June 1, 1914. Serial No. 842,267.

To all whom it may concern Be it known that I, JONAS TOROLF, a subjectof the King of Sweden, residing at Taft, in the county of Kern, State ofCalifornia, have invented certain new and useful Improvements inMountings for Sliding Doors, and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable Others skilled in the art to which it appertains to make and usethe same.

This invention relates to mountings for sliding doors.

The object of the invention resides in the provision of an improvedmounting for sliding doors whereby the door will partake of truehorizontal movement in opening and closing and binding of the doorduring such opening and closing movement positively eliminated.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter 'more fully described and particularly pointed out inthe appended claims.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several,

views, and in which Figure 1 is a View in elevation showing the improvedmounting associated with a sliding door, the latter being inopenposition; Fig. 2, a fragment of what is shown in Fig. 1 with thedoor in closed position; Fig. 3, a section on the line 33 of Fig. 2; andFig. 1, a perspective view of the connection between the door andstudding.

Referring to the drawings A indicates a sliding door frame including avertical studding 10, while B indicates a sliding door mounted in theframe A. Secured to the side of the studding 10 adjacent the door'B is aplate 11 to which is pivotally connected upper and lower arms 12 and 13respectively, said arms being of equal length. Secured to the edge ofthe door B adjacent the studding 10 is a plate 1 1 to which is pivotallyconnected upper and lower arms 15 and 16 respectively of a length equalto the arms 12 and 13, the pivot of the arm 15 being in the samehorizontal plane with the pivot of the arm 12, while the pivot of thearm 16 is dlsposed 1n the same horizontal plane with the pivot of thearm 13. The free ends of the arms 12 and 15 are pivotally mountedbetween the arms of a bifurcated member 17 and fixed to the free ends ofthe arms 12 and 15 are meshing segmental gears 18 and 19 respectively.The free ends ofthe arms 13 and 16 are pivotally mounted betweenthe"arms of a bifurcated member '20 and fixed to the free. end of the arms13 and 16 are meshing segmental gears 21 and 22 respectively. Thebifurcated members 17 and 20 are connected by a rod C formed of sections23 and 24 connected by a turn buckle 25 whereby said rod may belengthened and shortened.

From the foregoing construction it will be apparent that as the arms 12and 13 move down an equal movement will be imparted to the arms 15 and16 by reason of the meshing gears 18 and 19 and the meshing gears 21 and22 which will result in true horizontal movement of the door B towardthe studding 10. By reason of the connection between the door andstudding it will be obvious that the possibility of the door sagging andbinding is entirely obviated In the case of relatively light doors onepair of gears can be dispensed with but in the case of heavy doorsconnections between the door and studding of substantially the typeillustrated and described will be necessary to effect equal distributionof the strain throughout different parts of the connections.

What is claimed is 1. The combination with a vertical studding and ahorizontally sliding door, of one pair of upper and one pair of lowerarms pivotally connected to the studding and door respectively,unitingelements connecting the free ends of the upper and lower armsrespectively, meshing gears fixed to the free ends of one pair of arms,and a connecting rod between the upper and lower uniting elements.

2. The combination with a vertical studding and a horizontally slidingdoor, of one pair of upper and one pair of lower-arms pivotallyconnected to the studding and door, unitingelements connecting the freeends of the upper and lower arms respectively, gears fixed to the freeends of the upper and lower pairs of arms, the gears meshing on eachpair, and a connecting rod between the upper and lower uniting elements.

3. The combination with a vertical studpair of upper and one pair oflower arms pivotally connected to the studding and door, unitingelements connecting the free ends of the upper and lower arms respectively, gears fixed to the free ends of the upper and lower pairs ofarms, the gears meshing on each pair, a connecting rod between the upperand lower uniting elements, and means for lengthening and shorteningsaid connecting rod.

In testimony whereof, I affix my signature, in the presence of twoWitnesses.
